Pseudoephedrine Hydrochloride

Pseudoephedrine Hydrochloride is a sympathomimetic drug of the phenethylamine and amphetamine chemical classes used as a nasal/sinus decongestant and stimulant or wakefulness-promoting agent. The salts pseudoephedrine hydrochloride and pseudoephedrine sulfate are found in many over-the-counter preparations either as single-ingredient preparations, or more commonly in combination with antihistamines, guaifenesin, dextromethorphan, paracetamol (acetaminophen), and/or NSAIDs.

Pseudoephedrine is a diastereomer of ephedrine. Pseudoephedrine is a chiral molecule, meaning it occurs in both “left-handed” and “right-handed” configurations which are not superimposable.
